eeecontrol .3 now works for me. I think it would be helpful to somehow specify that this isn't changing the cpu frequency scaling algorithm but rather the fsb speed. Setting it to powersave seems to save about a Watt on my machine. Might be nice to have the tool change both the fsb and the scaling algorithm in the same window.

On the first page of this thread mawebb88 and hokal reported that their Atoms, without any outside help, ie before we started playing with commands to alter the fsb, that their result of running "cat /sys/devices/platform/eeepc/cpufv" were "768". From that, we deduce that the Atoms start from boot in Performance mode. I'd like to see some tests after the gui is installed and the fsb altered to see if the Atoms still boot in Performance mode by default . I suspect this will be the case.

Users on the forum at eeeuser.com report that they have been unsuccessful in overclocking it with the exception of those who have tried the Super Hybrid Engine (701SD apparently came with it installed) report being able to adjust clock speeds to 630MHz (underclock), 900MHz (default) and 960MHz (overclock).

OK, this confirms that the new 353-Celerons definitely should not be using the "/proc/eee/fsb" method for CPU FSB control.
They should be using the "/sys/devices/platform/eeepc/cpufv" method which is, in fact, SHE (Super Hybrid Engine) control.

Just to be clear here:
rhadon's Eee 900 and 01micko's Eee 701SD both have the new "353"-Celeron.
In theory, the Atom gui is the correct one for them. It uses the /sys/devices/platform/eeepc/cpufv
file for FSB speed.

The question remains: how do we differentiate between the two Celerons to help install the correct gui?

... OK, I just Googled for the output of "cat /proc/cpuinfo" of an Eee 700 (with older Celeron).
We already know that "model name" is the same as the faster Celeron
... but I see a difference:
"stepping : 6"
whereas the 353-Celeron has "stepping : 8"

A little strange the 2.49MHZ difference between rhadon's and my results but I guess voltages would be slightly different, different draws of current for different hardware and different power supplies._________________Puppy Linux Blog - contact me for access

And there will not be a change if you are using an Eeepc 701 SD. Unlike its 701 series counterparts the 701SD is set at 900MHz by default.However you should find the Super Hybrid Engine on the default Xandros that should allow you to underclock to 630MHz, return to the default 900MHz or overclock to 960MHz.

Read all the links you pointed me too and it certainly seems the only way to control the cpu freq on the 701SD is with SHE, (which looks like is owned by ASUS and probably closed source).

The p4-clockmod I suppose then is the stumbling block here? Xandros has a very old kernel, 2.6.1 but SHE does seem to work, no difference from performance to super-performance but powersaving shows a notable difference, however Puppy is faster overall. (No surprise there)
